[Manga] Engaged to the Unidentified

Engaged to the Unidentified
JP title: 未確認で進行形 (Mikakunin de Shinkoukei)

Synopsis (from Sentai Filmworks): Not every girl gets what she wants on her 16th birthday, but Kobeni's gift is something she never saw coming: an arranged marriage! Thanks to her late grandfather, Kobeni's been engaged to a total stranger since childhood, and even though she's supposedly met him she doesn't remember a single thing about him. Even weirder is that both her Mom and creepily over-doting sister, Benio, seem completely unsurprised when the groom-to-be, Hakuya, and his younger sister, Mashiro, show up on the family's doorstep to move in with them!

But it's not until they start attending Kobeni's school that things take an even stranger turn after she starts to pick up some very... unusual vibes from her potential future family. From Mashiro's obsession with aliens and UMAs (Unidentified Mysterious Animals) to Hakuya's disconcerting lack of emotion, there's something very off about them that Kobeni can't quite put her finger on. What has her grandfather gotten her into, and how does this relate to the strange gap in Kobeni's memory?

So the anime for this was really enjoyable, and I figured I'd rec the original 4koma here. The central romance is already really sweet, and with their sisters playing into things, it also gives the story more of a family comedy rather than just a straight-up rom-com. Oh, and there's some interesting supernatural elements too. And on top of all that, the publisher, Ichijinsha, is one JNC has already worked with, so that can make it easier for them to pick this one up. All in all, definitely something I'd like to see licensed on the manga side!
